Provided is, for example, a cleaner sheet including: a cleaning surface that is configured to be brought into sliding contact with a surface of an object to be cleaned. The cleaning surface has unevenness, and includes projections respectively having distal ends configured to be in sliding contact with the object to be cleaned when in use. The projections are constituted by a member formed to have the projections arranged at intervals from each other in a plane direction of the cleaning surface. The member has a hardness of 0.4 MPa or more measured by a nano-indentation method. The cleaning surface further includes adhesive recesses that have higher adhesive force than that of the member and are exposed on the cleaning surface.

Cleaner sheet, layered body of cleaner sheet, cleaning tool, and method for producing cleaner sheet

Provided is a sticky cleaner whose adhesive face can be easily renewed and whish is less susceptible to roll-loosening. The sticky cleaner provided by this invention comprises a PSA tape having an adhesive face on the first face of a substrate. The PSA tape forms a PSA tape roll wound with the adhesive face on the outside. On the first face of the substrate, the PSA tape comprises a first layer formed of a PSA and a second layer formed of an acrylic viscoelastic material. The adhesive face comprises first sections where the first layer is exposed and second sections where the second layer is exposed. The second sections protrude further out of the PSA tape roll relative to the first sections. The PSA tape roll shows an unwinding force Fat 0&#xb0; C. and an unwinding force Fat 30&#xb0; C.

Sticky cleaner

This invention provides a sticky cleaner used for removing organic dirt deposited on an article surface. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt upon contact with the article surface. The dirt-collecting member has an acrylic PSA in an area that comes in contact with the article surface. The dirt-collecting member exhibits a hardness of 90 or less in the area that comes in contact with the article surface.

A sticky cleaner is provided for use in removing organic dirt stuck on a surface of an article. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt as it makes contact with the surface of the article. The dirt-collecting member comprises a PSA at a part where it makes contact with the surface of the article. The PSA comprises, as its base polymer, an acrylic block copolymer having a hard segment (A) and a soft segment (B) in one molecule.

Sticky cleaner for removing organic dirt

Provided is a cleaner that can easily and efficiently remove organic dirt accumulated on a flat plate surface such as a display-input member (touch panel member) in a portable device. The cleaner () provided by the present invention is a pressure-sensitive adhesive plate surface cleaner () that comprises a pressure-sensitive adhesive body () having a removable pressure-sensitive adhesive and is used so as to allow the pressure-sensitive adhesive body () to contact a flat plate surface () of a plate such as a portable device () having a flat surface in order to remove organic dirt accumulated on the plate surface ().

Pressure-sensitive adhesive cleaner for plate surfaces

An adhesive tape roll at lower cost without reducing cleaning ability is provided. A release material layeras release means is provided in a streak shape on an adhesive surfaceof an adhesive tapewith the adhesive surfaceformed on one surface of the base material

Adhesive tape roll

Base film for pressure-sensitive adhesive tape and pressure-sensitive adhesive tape or sheet

A separator or a packaging material is provided, comprising a thermoplastic plastic film at least one surface of which is a matte surface or an embossed surface having a surface roughness (Ra) of not larger than 1/2 of the thickness of the film. The thermoplastic film may have a release treatment layer on the whole or part of a surface. The separator or packaging material is useful as a separator for pressure-sensitive adhesive articles and disposable articles or as a packaging material for packing foods, pressure-sensitive adhesive articles and sanitary articles. In particular, the separator is suitably used as a separator for a disposable diaper and a sanitary napkin, and also the packaging material is suitably used as a package for a sanitary napkin.

Separator or packaging material having a matte or embossed surface

Disclosed are an expandable fixing tape comprising a base material composed of an expandable portion and a substantially non-stretchable portion, and a fixing means provided on at least one non-stretchable portion which is present at one end of the base material, wherein the expandable portion exhibits a load of not more than 5.0 kg/25 mm at 200% expanding and a permanent set of not less than 30% under the condition of 200% expanding, and the substantially non-stretchable portion has a ductility of less than twice under a load of not more than 0.5 kg/25 mm and a base material composed of an expandable portion, which is a thin layer portion having a thin thickness, at the central portion in the lengthwise direction and substantially non-stretchable portions, which are thick layer portions having a thick thickness, at both the end portions, a fixing means provided on at least one non-stretchable portion which is present at one end of the base material, wherein the expandable portion can be expanded to the length of at least three times under a load of 1.5 kg/25 mm and has a permanent set of at least 30% under the condition of 200% expanding, and the thickness of the expandable portion is not more than 90% of the thickness of the non-stretchable portion. These tapes can be easily expanded by a weak force at use and are very practical and easily usable, and are suitably used for packaging bags, boxes, etc. or for treating sanitary articles used.

Expandable fixing tape

Double-sided pressure-sensitive adhesive tape, laminated structure

A fixing tape is disclosed, which comprises a plastics film having a two- or three-layer construction comprising a plastics film layer and a polymer blend layer formed on at least one side of the plastics film layer, one side of the polymer blend layer facing away from the plastics film layer being a satin surface.

Fixing tape

A pressure-sensitive tape, a pressure-sensitive tape-fixing structure comprising a member made of a material having a rough surface, having fixed thereto the pressure-sensitive tape, and a roll of the pressure-sensitive tape are disclosed, the pressure-sensitive tape comprising a pressure-sensitive tape comprising a tape substrate, a first pressure-sensitive adhesive area provided on one side of the tape substrate in a tape substrate part which is close to one end of the tape substrate, and a second pressure-sensitive adhesive area provided on one side of the tape substrate in a tape substrate part which is close to the other end of the tape substrate, wherein either or both of said first pressure-sensitive adhesive area and said second pressure-sensitive adhesive area have a strongly adhesive area at an end part thereof to which an external peeling force is to be applied first, and said strongly adhesive area has a peel strength higher than that of the other part of the pressure-sensitive adhesive area.

Pressure-sensitive tape, pressure-sensitive tape-fixing structure, and

A plastics film having a two- or three-layer construction comprising a plastics film layer and a polymer blend layer formed on at least one side of the plastics film layer, one side of the polymer blend layer facing away from the plastics film layer being a satin surface.
